Another theme is personal growth. In 'Horimiya', both Hori and Miyamura grow as individuals as they fall in love. Hori learns to be more open about her true self, and Miyamura gains more confidence. The relationship between the big girl and the short boy serves as a catalyst for their development.
One common theme is the idea of breaking stereotypes. Usually, there are certain expectations about how couples should look like in terms of height and build. In these stories, they defy those norms. For example, in 'My Love Story!!', Takeo doesn't fit the typical image of a romantic lead because of his large size, but his relationship with Rinko shows that love doesn't depend on appearance.
The theme of acceptance is also prevalent. In 'Toradora!', Taiga and Ryuuji have to accept each other's flaws and quirks. Despite their differences in height and personality, they come to understand and love each other for who they are. This acceptance is a key part of the love story in many such animes.
One common theme is the initial self - consciousness. The short boy might feel insecure about his height compared to the tall girl, and vice versa. For example, in some stories, the boy may worry that he doesn't look 'manly' enough beside the taller girl. Another theme is the breaking of stereotypes. They often go against the typical image of a 'tall and strong male' and 'short and petite female' couple. It shows that love can exist between two people regardless of physical differences.
There's also 'Horimiya'. In this anime, Hori is a popular girl who has a different side to her at home, and Miyamura is a seemingly quiet and short boy with piercings and tattoos (hidden at school). Their relationship starts in an unexpected way as they get to know each other better outside of school, and it gradually turns into a sweet love story.
Growth. As they fall in love, the bad boy and bad girl usually grow as characters. In 'Kimi ni Todoke', Sawako, who was seen as an odd girl, and Kazehaya, a popular boy, both grow and learn from their relationship. They change for the better, leaving behind some of their 'bad' traits as they develop a deeper connection.
Conflict is also a major theme. Their personalities, which are often headstrong and independent as 'bad' characters, lead to a lot of clashes at first. However, these conflicts also add spice to their love story as they learn to understand and accept each other over time.
A theme could be unexpected love. In 'Toradora!', Ryuuji never expected to fall in love with Taiga. They were so different and had other initial goals. But love just happened in an unexpected way. Also, friendship turning into love is a common theme. In many of these anime, the characters start as friends or at least friendly acquaintances, and then gradually develop deeper feelings for each other.
One common theme is unrequited love. For example, the boy may love the girl deeply but the girl may not feel the same way. Another theme is separation. It could be due to distance like in the case where one has to move away. Also, family or social pressure can be a theme. For instance, families not approving of the relationship can lead to a sad ending.
One common theme is separation. Like in the story where the boy has to move away. Another is illness, which can tear a couple apart. Also, external factors such as family or work problems often play a role.
Growth and self - discovery are also often seen. In a story, a boy and a girl may learn something about themselves while interacting with each other. They might realize their own strengths and weaknesses, like a girl who is always timid but becomes brave when helping a boy in trouble. And the boy might learn to be more patient through their relationship.
One such anime could be 'My Love Story!!'. In this anime, Takeo Gouda is a tall and rather intimidating - looking boy with a heart of gold, while Rinko Yamato is a petite and cute girl. Their relationship develops in a very sweet and endearing way, filled with many heart - warming moments as they navigate their feelings for each other.
A common theme is self - discovery. The poor girl may discover her own worth beyond her financial situation through the relationship. And the rich boy might learn about the simplicity and real values in life from the girl. Also, there's the theme of sacrifice. Sometimes one or both of them have to sacrifice something, like the rich boy giving up his family's inheritance or the poor girl sacrificing her own dreams to be with the one she loves.
